What this research studies

We know that the sympathetic nervous system plays a role in pain and inflammation, and blocking it can help with neuropathic pain like CRPS. Our past work has shown that active nerve regeneration and immune responses are key to persistent pain. This project explores how nerve growth and its interactions with sensory nerves and immune cells contribute to pain. We are also looking at how removing a nearby lymph node might reverse these pain-related processes, suggesting new ways to manage chronic pain.

Who could benefit from this research

Good fit: Patients experiencing chronic neuropathic pain, such as CRPS, might eventually benefit from treatments developed from this understanding.

Not a fit: Patients with pain not related to nerve injury or sympathetic nervous system activity may not directly benefit from this specific line of research.

Why it matters

Potential benefit: This work could lead to new ways to manage chronic neuropathic pain by targeting nerve growth and immune responses.

How similar studies have performed: A recent clinical study using a catheter for sympathetic blockade showed promising results for intractable neuropathic pain, suggesting related approaches can be effective.
